Ninth International Conference on Food Studies

Abstract

Because of economic and social concerns, bio-energy is likely to continue to attract further interest, research, and development in the wastewater industry. The role of bio-energy production in the context of wastewater treatment/re-use will increasingly engender positive changes in society’s attitudes and perceptions. Furthermore, an evaluation of bio-processed fruit waste into an added value by-product. Other parameters investigated include development of pre-treatment procedures, bio-process kinetics, and design/operation criteria. A relationship of required aeration time, pH, dissolved oxygen, and oxidation reduction potential curves during yeast growth was developed. The protein enhanced product from the bio-process fruit waste was subject to a shrimp feeding trial. It was found that it provided a similar cumulative mean growth as commercial feed and similar cumulative FCR (feed conversion ratio) as a controlled diet. This combined effort of treatment may provide an effective utilization of an existing wastewater treatment system as well as an affect on the food waste management system to achieve a sustainable environmental system.
